3 Claims.

This invention relates to a powder gun, and it is an object of theinvention to provide a gun of this kind comprising a top and bottommember having meansinterposed therebetween for urging said members onefrom the other and wherein the bottom member carries an outwardlydisposed spout.

It is also an object of theinvention to provide a device of this kindincluding a top memberand a bottom member connected by a flexible sidewall, together with a coiled spring interposedbetween the top and bottommembers operating to urge said members one away from the other, one ofsaid members being provided, with afilling opening and the other of saidmembers carrying an outwardly directed discharge spout.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved powdergunwhereby certain important advantages are attained, as will behereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawing,wherein:

Figure 1 is aview in side elevation, with a portion broken away, of apowder gun constructed in accordance with an embodiment of my inven-'tion.

Figure 2 is a vertical sectional view taken sub stantially radiallythrough the device as illustrated in Figure 1.

Figure 3 is a fragmentary sectional view illustrating a gun constructedin accordance with another embodiment of my invention, and

Figure 4 is a sectional view taken substantially on the line 4--4 ofFigure 3.

As disclosed in the accompanying drawing, A denotes a top member and B abottom member, each being formed of metal or other suitable materialpossessing requisite strength and resilience. These members A and B arecup-like and the side walls 1 and 2 respectively are inwardly disposedand are relatively short.

The member A at its central part is provided with a relatively largefilling opening 3 and the marginal portion of the member A defining saidopening 3 is formed to provide a rounded bead 4 to facilitate theapplication or removal of the closure plug 5 or cork or other preferredmaterial.

The bottom member B is provided in its side wall 2 with an opening 6through which is inserted from within an elongated tapered dischargespout l. The inner or larger end of the spout l is provided with asurrounding flange or bead 8 which has close contact with the inner faceof the side wall 2 of the bottom member B. The inner or larger endportion of the spout I tightly wedges within the opening 6. However,

to further hold the spout I in applied position,

solder or the like may be employed and applied at both sides of the sidewall 2.

The members A and B are connected by a cylindrical side wall C of redrubber or other flexible cloth or material. .Interposed between themembers A and B is a helical spring 9 herein disclosed as comprising sixcoils. One end portion of this spring 9 is snugly received within themember A and has contact with the head I9 thereof while the opposite endportion of the spring 9 is snugly received within the member B and hascontact with the head ll thereof.

This spring 9 has each of its coils of a diameter substantially equal tothat of, the members A and B and said spring 9 is ofsuiiicient tensionto constantly urge the members A and Bone away from the other for amaximum distance determined by the length of the cylindrical side wallC. It will also be noted that the coilsiof the spring 9 are of suchdiameter as to maintain the side wall C distended at all ,timesftoassure proper discharge out through the spout i when pressure isimposeduponthe members A and B or either of said members. I v V Inassembling thev device, the member A with its head" I0 innermost isinserted within an end portion of the cylindrical side wall C and saidend portion ofthe cylindrical side wall' C is securely heldto the sidewall- I of the ,membe'rA adjacent the outer end portior'i' thereof by anencircling strand l2, preferably wire, and which strand forces theadjacent portion of the side wall C within a surrounding groove I4pressed in the side wall I of the member A. After this securement of thecylindrical side wall C to the member A, said cylindrical side wall C isturned inside out so that the major portion of this side wall C willextend beyond the free end of the side wall I of the member A. Thespring 9 is then applied, after which the bottom member B has its sidewall 2 inserted within the end portion of the side wall C remote fromthe member M.

This side wall C is securely held to the side wall 2 of the member B byan encircling strand I5 of wire or the like, which strand l5 tightlypresses th adjacent portion of the side wall C within a surroundingroove 16 pressed in the side wall C of the member B adjacent the outerend thereof. After this connection between the member B and the sidewall C, a band ll, preferably of rubber, is applied around the endportion of the side wall C connected to the side wall 2 of the member Bto conceal the strand l5 and thereby improve the appearance of the gunand at the same time to provide further means for maintaining thedesired connection between the side wall C and the member B.

In the embodiment of the invention as illustrated in Figures 3 and 4,the'bottom member D of the gun is provided with means to avoid lumpingof the powder when discharged out through the spout I8. This spout I8 isalso tapered and is inserted from within out through an opening i9provided in the side wall 20 of the member "D.

The inner or larger end portion of the spout l6 extends a distanceinwardly of the member D and said inserted end portion is tightlystraddled by an end portion of a filtering member 29 within;

the member D and extending radially thereacross.

This member is of metal or other suitable material possessing sufiicientrigidity and, as illustrated in Figure 4, is substantially in the formof an inverted U with its longitudinal edges provided with the outwardlydisposed flanges 2| to facilitate solderin of the member '20 to the head22 of the member D. This member 20 is provided with the perforations 23of a size to allow powder to readily pass therethrough' but to filterout or hold back any lumps. This member 20 also has a tendency to breakup the lumps within the powder when the powder content is underpressure.

From the foregoing description it is thought to be obvious that a powdergun constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itma be assembled and operated.

What is claimed is:

1. A powder gun comprising a top member havin a side wall, a bottommember having a side wall, the side wall of one member bein disposedtoward the side wall 'of the secondmember, a flexible tubular side wallinterposed between the top and. bottom members, the side walls'of saidmem-' bers extending within the opposite end portions of the tubularside wall, one end portion of the tubular "side wall being inwardlyreverted, a flexible strand surrounding said reverted portion forclamping the same to the side wall of one of the members, said strandbeing between the reverted portion and the side wall proper whereby saidstrand is entirely concealed, a flexible strand encirclin'g'the oppositeend portion of the tubular side wall for anchorin the same to the sidewall of the second member, a coiled spring interposed between the topand bottom members, the tubular side wall surrounding said spring, and aspout carried by one of the members and extending out through the sidewall thereof.

2. A powder gun comprising a top member having a side wall, a bottommember having a side wall, the side wall of one member being disposedtoward the side Wall of the second member, a flexible tubular side wallinterposed between the top and bottom members, the side walls i of saidmembers extending within the opposite end portions of the tubular sidewall, one end portion of the tubular side wall being inwardly reverted,afiexible strand surrounding said revertedportionfor clamping the sameto the side wall'bf one of the members, said strand being between thereverted portion and the side Wall proper whereby said strand isentirely concealed, a'flexible strand encircling the opposite endportion of the tubular side wall for anchoring the same to the side wallof the second member, a coiled spring interposed between the top andbottom members, the tubular side wall surrounding said spring, a spoutcarried by one of the memhers and extending out through the side wallthereof, and a band tightly surrounding said opposite end'portion ofthe'tubular side wall and the side wall of the associated end member andcovering the second mentioned strand.

, 3. A powder gun comprising two circular members each having asurrounding side wall, the members being'arranged with the edges of theside walls in' opposed relation, a flexible tubular side wall extendingbetween and connected at its ends to the side walls of the circularmembers, the side wall of one circular member having an openingtherethrough, an elongated screen element of substantially U-sha'pedcross section disposed across the said one circular member and securedbetween opposite sides of the side wall thereof, one end of said screenbeing alined with said opening and the said screen being disposed with'its open side opposed to the adjacent circular member and in contacttherewith, a tubular [discharge spout havin anfend inserted throughsaidopening intoand firmly secured in the adjacent end of the screenmember, and a coiled spring within and extending through the flexibletubular side wall and bearing at one end upon the screen member andhavingits other end engaged in the opposite circular member.
